new `and useful Improvements in Gluing- Ma'chlries, of which the following 1s a speciication.

This invention relates to gluing machines, and more particularly to machines for apply-- ing glue to one side of a sheet of paper, like a label.

The object of the invention is a device of few wearing parts,` and which is readily accessible for cleaning.

The novel features of the machine will be disclosed in the course of its description.

In the drawings: Figure 1 is a plan view of the gluer; Fig. 2 is a section on the line 2-2 of Fig. 1 Fig. 3 is an elevation viewed in the opposite direction to Fig. 2; Fig. 4 is an elevation of a detail; Fig. 5 is a section on the line 5 5 of Fig. 4; Fig. 6 is a partial' top lan view of a detail (enlarged), and Fig. 7 1s an elevation of the parts shown in Fig. 6.

The gluing apparatus is attached to a pair of side-frames 1, 1, which are screwed to a table top 2. Said frames are held rigidly together by bolts 3, which pass through lugs in an inclined plate 4. The latter forms a support for a wedge-shaped glue-pan 5, and also for a steam-box 6, whereby the glue contained in said pan may be heated. The pan 5 is prevented from sliding down ofl the. plate 4.by an u wardly projecting lug 7.

. The glue-rolFS is supported horizontally on a shaft 9, which is revoluble in bearings 10. Said shaft carries, outside of the frame 1, a gear 11 and a driving pulley 12. The roll 8 is so proportioned as to dip into the glue contained 1n the pan 5.

A rock-shaft 13 is supported horizontally in the frames 1 beneath the plate 4, and au arm 14 is fixed to each end of said shaft. A wiping-roller 15 is revolubly supported in the upper ends of the arms 14, and carries upon f its shaft a gear 16, that is smaller than the gear 11, and meshes with it. An arm 1? is also ixed to the shaft 13, midway between the frames 1, and approximately parallel to the plate 4. A thumbscrew 18 extends through the outer end of said arm, and enters the said late 4. A spring 19 is coiled about the shan of the thumbscrew 'l S, and

tends to force the arm 17 downward. Accordingly, by turning the thumbscrew 18 to the right, the arm 17 will be lifted, thereby rocking the shaft 13 and moving the arms 14 forward, Iso that the wiping-roller 15 is brought very close to or into actual contact witlrthe glue-roll 8. On turning the thumbscrew 18 in the opposite direction, that is to the left, the spring 19 forces the arm 17 downward, and the wiping-roller 15 is thus moved away from the glue-roll 8. -lf the thumbscrew is turned sufliciently the gear 16 is thrown entirelyT out of mesh with the gear 11.

The rolls 8 and 15 turn as shown by the arrows, and their adjacent peripheries therefore both move in the same direction. The gears 1l and 16 are, however, so proportioned that the roll 8 turns faster than the roller 15, and so the latter acts as a wiper, holding back surplus glue that adheres to the surface of the roll S.

The feed-rolls overy which the labels, etc. are passed to the glue-roll 8 are su )ported in alinement with the top of a fee -table 20. The lower feed-roll 21 is revoluble in fixed bearings 21, and carries on its outer end a pinion 22, which engages the ear 16. The upper feed-roll 23 is supporte in plates 24, 24, which lie, respectively, in grooves 25, 25, in the side-frames 1, 1. Said plates may be moved backward or forward independently of each other, and, respectively, secured in the desired )osition by bolts or screws 26, 26. The feed-roll 23 is therefore adjustable in the horizontal plane, for thepurpose of determining the angle at which the label shall approach the glue-roll 8. The said roll 23 lies within the open vertical guide-ways 27 (Fig. 4), and rests upon the roll 21, so that it is rotated by the latter.

Labels or other papers when pushed along the table 20 enter between the feed-rolls 21 and 23, and are fed by them onto the glueroll 8. The pinion 22 is so proportioned that the peripheral speed of said feed-rolls is less than that of the glue-roll, and thus the paper is retarded, and the glue is distributed very separate the label from the glue-roll as it is carried over on the top of the latter. Said pickers consist of bars, pivoted on a rod 3() which rests in suitable supports 29, 29 in the `without removin side-frames l, l, respectively. Each bar 28 has at itsupper end a diamond-shaped piece 31, which has a knife-edge at each end, and can be reversed when one edge grows dull.

The gluean 5 is made in the form shown in Fig. 2 so t at it may be easily removed for cleaning." To remove said pan, its lower end is lifted up sufliciently to clear the lug 7, when the pan may be withdrawn, the rear end being shallow enough to pass under the glueroll 8.

Another advantage in having the glue-pan in an inclined position is that the glue is kept in motion and revented from settling or solidifying, for t e movement of the roll 8 tends to push the upper strata of glue up the incline, which in turn causes the lower strata to move downward, a constant circulation beivxglthus maintained.

en the glue is used up to such an extent that the roll 8 no longer touches it, the gan 5 may be moved up alon the plate 4, an will be held in place by t e roughness of said' plate, or suitable means. The level of the glue is thus capable of being raised with reference to the roll 8.

If desired, a screen 5? may be placed in the lpan 5, to strain sediment out of the glue.

ain, fresh gle ma be poured into the pan t e latter from its su,-

portf but to do t s the pickers 28 must e thrown forward, and the glue poured bel tween the rod and the roll 8.

What I claim is A 1. In a gluing machine, the combination of a suitable frame; a glue-roller journaled' therein; a rock-shaft parallel with said glueroller, having an upwardly extending arm at each end, and the outwardly extending arm 17 between them; a wiping-roller rotatively supported in said u wardly extending arms, adapted to engage t e glue-roller and an adjustable connection between a fixed part of the machine and said intermediate arm 17 on the rock-shaft for adjusting the wiping-roller with reference to the glue-roller consisting of the thumb screw 18 andthe s ring 19; substantially as shown and descri ed. 2. In a gluing machine, the combination of a suitable frame; a glue-roller journaled therein; a pair of feed rollers both parallel with said glue-roller, consisting of a lower roller that is revolubly supported in xed bearings, and an adjustable upper roller; a'

plate 24 at each end of said'u per roller, slotted vertically to receive'an support it revolubly, and in turn contained, respectively, within parallel grooves 25, 25 in the frame', whereb said plates are horizontally adjustable Wit reference to the glue roller; and means for securing them in position; substantially as shown and described.
